Spectrum Color Illuminance Meter STC-4000

Integrates spectrum, illuminance, color temperature, color rendering index, R9, wavelength, irradiance, chromaticity coordinates, color tolerance and other measurement parameters in one. Using 5-inch large screen, all parameters and curves displayed in real time, easy to use. Can measure LED and other wide spectrum light sources, as well as home and commercial lighting, eye-protection desk lamps, classroom luminaires, high and low pressure sodium lamp HID and other narrow spectrum light sources.
